AMAZING SPIDER-MAN #13 (1964)

So in just five panels, we see a great conversation showing Flash to be a complete idiot–complete with a wonderful Ditko double-take; Betty is starting to actually dig Peter, as a result of his newfound confidence; and we meet….Mysterio.

This is the kind of stuff that wasn’t iconic when it was created. It was pulp printed on newsprint. But it’s some of America’s greatest art. Seriously.
